(Hennepin Co., MN) — A forensic pathologist called by Derek Chauvin’s defense team says there wasn’t one sole cause of George Floyd’s death. On Wednesday, Doctor David Fowler testified he thinks there were several factors contributing to Floyd’s death. One factor he suggested was carbon monoxide poisoning because of how close Floyd was to the squad car’s exhaust when he was being restrained by Chauvin. The prosecution could bring a rebuttal witness today. The defense is also expected to rest its case today.
